The co-founder of the Leave means Leave campaign suggested pro-Remain political figures are the cause of the UK’s struggles during negotiations with Brussels.
Mr Tice said: “One of the reasons we’ve struggled with our negotiations is because people in Westminster have been completely undermining our negotiating leverage.
“They have shown unity in the European Union.”
Brexiteers like Mr Tice condemned the latest Brexit deal proposals, claiming the Government had made too many concessions to the EU.
He added: “Here we have people in Westminster, Remainers who are completely undermining our negotiations.”
The proposals would see Britain enter a 21-month transition period during which it would abide by EU regulation – including the controversial Common Fisheries Policy (CFP).
Mr Tice voiced his concern about possible concessions the Government could make to Brussels that would ultimately harm British fishermen.
The pro-Brexit campaigner called on the Government to protect the industry and make clear any attempt from the EU to extend its control after Brexit would derail negotiations.
He told BBC Any Questions?: “Over fifty years ago, the fishing industry in this country got completely shafted on the way into the EEC and they have serious justifiable concerns that they are not going to be sold down the river in this deal.
“What really troubles me is suggestions one hears in London that, for example, the Government might be prepared to do some sort of trade-off deal and sell the fishermen down the river in favour of financial services.
“It’s absolutely vital the Government, indeed the Prime Minister makes it crystal clear it’s a red line on which we would be prepared to walk away.”
